A cell is the basic unit of living organisms (both plants and animals)
that is capable of reproducing itself exactly. That is, there are
components within cells (organelles), but they do not reproduce themselves
independently of the cell(s) of which they are a part.
All cells contain organelles.
These are structures within the cell
that are specialised for particular functions.
Examples include: nucleus, rough
endoplasmic reticulum (RER), smooth
endoplasmic reticulum (SER), Golgi
apparatus, lysosomes, mitochondria,
etc.. See the Revision page about Cell
Structure for further information including a diagram of the
structure of a basic cell including the nucleus, nucleolus,
etc.. |
